Tiber - History

History

According to legend, the city of Rome was founded in 753 BC on the banks of the Tiber about 25 kilometres (16 mi) from the sea at Ostia. The island Isola Tiberina in the centre of Rome, between Trastevere and the ancient center, was the site of an important ancient ford and was later bridged. Legend says Rome's founders, the twin brothers Romulus and Remus, were abandoned on its waters, where they were rescued by a she-wolf.

The river marked the boundary between the lands of the Etruscans to the west, the Sabines to the east and the Latins to the south. Benito Mussolini, born in Romagna, adjusted the boundary between Tuscany and Emilia-Romagna, so that the springs of the Tiber would lie in Romagna.

The Tiber was critically important to Roman trade and commerce, as ships could reach as far as 100 kilometres (60 mi) upriver; there is evidence that it was used to ship grain from the Val Teverina as long ago as the 5th century BC. It was later used to ship stone, timber and foodstuffs to Rome.

During the Punic Wars of the 3rd century BC, the harbour at Ostia became a key naval base. It later became Rome's most important port, where wheat, olive oil, and wine were imported from Rome's colonies around the Mediterranean. Wharves were also built along the riverside in Rome itself, lining the riverbanks around the Campus Martius area. The Romans connected the river with a sewer system (the Cloaca Maxima) and with an underground network of tunnels and other channels, to bring its water into the middle of the city.

Wealthy Romans had garden-parks or "horti" on the banks of the river in Rome up through the first century BC. These may have been sold and developed about a century later.

The heavy sedimentation of the river made it difficult to maintain Ostia, prompting the emperors Claudius and Trajan to establish a new port on the Fiumicino in the 1st century AD. They built a new road, the via Portuensis, to connect Rome with Fiumicino, leaving the city by Porta Portese ('the port gate'). Both ports were eventually abandoned due to silting.

Several popes attempted to improve navigation on the Tiber in the 17th and 18th century, with extensive dredging continuing into the 19th century. Trade was boosted for a while but by the 20th century silting had resulted in the river only being navigable as far as Rome itself.

The Tiber was once known for its floods — the Campus Martius is a flood plain and would regularly flood to a depth of 2 metres (6 ft 7 in). The river is now confined between high stone embankments which were begun in 1876. Within the city, the riverbanks are lined by boulevards known as lungoteveri, streets "along the Tiber."

Because the river is identified with Rome, the term "swimming the Tiber" has come to be the Protestant shorthand term for converting to Roman Catholicism. This is most common if the person who converts had been Anglican, the reverse of which is referred to as "Swimming the Thames."

In ancient Rome, executed criminals were thrown into the Tiber. People executed at the Gemonian stairs were thrown in the Tiber during the latter part of the reign of the emperor Tiberius. This practice continued over the centuries. For example, the corpse of Pope Formosus was thrown into the Tiber after the infamous Cadaver Synod held in 897.
